Description
Technical field
What the present invention relates to is a kind of wire harness clamping device of spin spindle or twisting spindle.
Background technology
Said device is equipped with second clamping element that one first clamping element and can move with respect to first clamping element; When in the closed position; Yarn is sandwiched in the clamping region between first clamping element and second clamping element; When being shown in an open position, yarn is not clamped, and second clamping element can move between closed position and open position.This device also is furnished with at least one load elements in addition, is responsible for applying load force to second clamping element, and under the help of this element, second clamping element is parked in the closed position at least when the wire harness clamping device remains static; This device also is furnished with at least one unloading element; This element can apply a unloading force (this power and load force are relative) by the centrifugal force decision to second clamping element when the wire harness clamping device rotates; Under the help of this element, second clamping element can move to open position from the closed position under a certain specified rotation number of wire harness clamping device.
Such wire harness clamping device had been done introduction in such as patent documents such as DE196 28 826 A1 or EP 2 024 265 B1, it is mainly used in when changing full line bobbin for spinning machine or wrapping machine fixing so-called around yarn.
Therefore on the corresponding generally speaking wire harness clamping device two clamping elements that can relatively move are installed all; Usually one of them clamping element is installed on the rotary type top of Yarn-spinning spindle or twisting spindle; And not rotatable, be used for fixing the bobbin that spins yarn and also be installed in this position.In contrast, second clamping element is installed in the axial direction with respect to rotary type top, and can move, and this element can remain on closed position above-mentioned by spring under a certain revolution of Yarn-spinning spindle or twisting spindle.
In order this transportable clamping element to be moved to open position, the yarn that makes it to clamp with first clamping element in this position discharges certain anchor clamps slit, and one or more unloading elements also are installed respectively on the wire harness clamping device now.They can be that for example spheroid is formed, and closely paste mutually with the intilted taper ring surface of clamping element movably.When the revolution of Yarn-spinning spindle or twisting spindle increases, this spheroid is applied outside centrifugal force.In this case, they the most at last power be delivered on the ring surface, ring surface orders about removable clamping element and moves along the direction of principal axis on rotary type top, thereby opens the anchor clamps slit.
When the spindle revolution dropped to a certain degree, the outside centrifugal force that spheroid is applied also can reduce thereupon, still maintained open position until not enough so that second clamping element overcomes the load force of spring.This moment, this clamping element moved once more, closed the anchor clamps slit and clamp to be placed on the yarn in the anchor clamps slit.Line cuts off the most at last in this position; Replace bobbin empty with a full line bobbin; The line that still will come out with the clamp spinning and the place of twisting thread this moment increases until the revolution of Yarn-spinning spindle or twisting spindle again, is enough to clamping device is movably retracted open position again.Spun line was reeled through corresponding oneself and was twined on the bobbin this moment, when changing bobbin, just was necessary to clamp yarn with the wire harness clamping device next time.
Yet in general, known wire harness clamping device all has a shortcoming at present, promptly must between two clamping elements, leave a slit, so just might realize the relative motion between first, second two clamping elements.Also produce a slit (even very little) so simultaneously, made external contamination thing (the for example part of yarn) may be penetrated into the inside of wire harness clamping device.These pollutants may accumulate in the unloading element area at last, and the worst situation is exactly because the frictional force influence of pollutant makes the unloading element can not drive removable clamping element again and moves to open position.
Summary of the invention
Therefore target of the present invention just be into Yarn-spinning spindle or twisting spindle design compared to existing technologies a kind of, the lower wire harness clamping device of risk that pollutant infiltrates.
Through a wire harness clamping device that has the said characteristic of claim 1, just can realize this goal.
According to design concept of the present invention; Suggestion is installed at least one and is had the retainer of stop surface on this wire harness clamping device; Second clamping element closely pastes with stop surface through outer surface when open position at least mutually, thus prevent contaminant infiltration in the retainer zone to this wire harness clamping device in the inner chamber that unloads element.On traditional wire harness clamping device, a slit of leading to device external is arranged all usually between first clamping element and second clamping element.Now on the wire harness clamping device that the present invention relates to, through will before the tight method of subsides mutually of outer surface and retainer of second clamping element that mention, outwards seal this slit at the open position of second clamping element movably at least." outer surface " here is meant the limiting faces of the outside side of second clamping element in the whole operation process of wire harness clamping device, and second clamping element is to be combined by a plurality of independent parts.Retainer is at the wire harness clamping device preferably on the installation region; Preferably guarantee to see from the outside first clamping element in the closed position and the slit between the second clamping element appropriate section movably, because just in time need prevent this regional endosmosis pollutant.
For example, the wire harness clamping device that the present invention relates to can be installed first clamping element that is sleeve-shaped basically, and this element preferably is fixed on above the rotary type top of Yarn-spinning spindle or twisting spindle.On this first clamping element, one second clamping element can be installed again, this clamping element also can be a sleeve-shaped.In this case, these two clamping elements have constituted a concentric ring body, leave the slit of certain necessity between the two, make these two relatively moving of clamping element and can not produce bigger frictional force.
The outside is generally all led in this slit.The wire harness clamping device of the present invention's design then is equipped with a retainer, closely pastes mutually with it when being shown in an open position at second clamping element (usually around first clamping element), thereby can effectively avoid contaminant infiltration to arrive in this zone at least.At last it is pointed out that also that in this position retainer can be installed on second clamping element face far away apart from clamp segment, for example is installed on its positive end face.
It presents circle or annular when overlooking stop surface, if adopt second clamping element of sleeve-shaped so, then can bring special advantage.If the last sealing contact that when second clamping element is shown in an open position, has reached expection between two clamping elements and the retainer, then these two parts have just constituted the integral body that can outwards surround first clamping element at least in the retainer zone.So just stopped pollutant and be penetrated into the possibility in the equipment, thereby avoided unloading element (for example spherical in shape) to result in blockage inside from this place.
In addition, retainer is restrainted the axial direction of clamping device along the line to second clamping element motion constitutes restriction, and this has also brought other advantages.Can omit the module that inside is used for limiting the motion of second clamping element in this case.Also can guarantee of the security of second clamping element thus, and closely paste mutually, and need not to have considered the corresponding acceptable tolerance of internal limitations module again with stop surface at open position.
No matter second clamping element is shown in an open position still closed position, and retainer all contacts with first clamping element, and such design is favourable equally.If present second clamping element contacts with retainer at open position equally, and closely paste mutually, thereby connect the slit of having risen between two clamping elements at this position retainer and two clamping elements.In this case, retainer prolongs piece with this and couples together as the prolongation piece of first clamping element on wire harness clamping device direction of principal axis when second clamping element is shown in an open position.
Further, if retainer is fixed on first clamping element, also be favourable.This moment, first clamping element and retainer were formed a unified structure unit, and this connection can guarantee not have pollutant from being penetrated into the position of unloading element between first clamping element and the retainer.The clamping element here can only be made up of a part, and links together through power engagement and/or form fit and retainer.
If at least one section of the retainer and first clamping element is formed a unified assembly, is favourable equally.In this design, there is not tie point between the retainer and first clamping element, thereby stopped fully from the possibility of this position endosmosis pollutant.Move to the direction of retainer if under the effect of the power that the unloading element produces, order about second clamping element now, when it finally reaches open position, will as expecting, closely paste mutually so with retainer.The result is exactly that slit between the closed position retainer and second clamping element has been closed.And said structure has determined also can not exist between first clamping element and the retainer slit, has therefore realized to external seal effectively through retainer on first clamping element and this position of second clamping element.In the retainer scope, got rid of dust or other contaminant infiltration possibility basically to device interior.
When stop surface during, also have superiority perpendicular to the moving direction of second clamping element.This moment, second clamping element can lean against on the retainer at open position especially exactly, and retainer is used to limit moving of second clamping element conversely.The retainer here is structure ringwise, and it both can be fixed on first clamping element, also can as hereinafter will specify, be fixed on the rotary type top of the mutual twisting spindle of Yarn-spinning spindle, and first clamping element also is installed in this position.
If the profile of the outer surface of second clamping element (but its when being shown in an open position its outer surface link to each other with stop surface) and the profile of stop surface coincide each other, also has advantage.So, second clamping element just can be close to stop surface especially exactly.Although any desired contour all is feasible in principle, several kinds of structures that can embody advantage have especially been introduced below.
For example the Cross-section Design with retainer and stop surface is a stepped construction, is exactly a kind of useful thinking.Opposite with the plane formula stop surface, this design can increase the contact area of the retainer and second clamping element, thereby further reduces contaminant infiltration to the inner danger of wire harness clamping device.This moment, retainer was preferably designed as loop configuration, and had a zone when second clamping element is shown in an open position, to contact with two clamping elements simultaneously above it, thereby can conscientiously the slit between two clamping elements from inside to outside be sealed up.
If the annular shoulder spare with retainer constitutes at least a portion stop surface, also is a very favourable thinking.This moment, retainer was preferably loop configuration, was fixed on the rotary type top or first clamping element of the mutual twisting spindle of Yarn-spinning spindle for example, was the part of the element mentioned.If second clamping element is a sleeve-shaped, can imagine that so part is protruding in sleeve inner in the closed position for second clamping element, and combines each other with retainer in this way.Corresponding part finally demonstrates two concentric circles that interweave and arrange with the cross section of second clamping element in this position on the retainer.If second clamping element moves to open position, then it receives the guiding of that part of mentioning on the retainer in radial direction, axially partly contacts with the annular shoulder spare of retainer at open position at last.
In addition, if the overall diameter of at least one section of retainer reduces on the unloading component orientation gradually, also be favourable.If second clamping element of this moment is in the closed position, between the stop surface of outer surface that its open position contact with retainer and retainer, understand outwardly open annulus of appearance so.This annulus and adjacent in wire harness clamping device slit inner, that between unloading position of components first clamping element and second clamping element, occur.If this moment, the wire harness clamping device began rotation, the air at place, annulus can produce centrifugal force equally so.Along with the diameter of annulus constantly increases, this strand centrifugal force also increases gradually.Because the structure of retainer above-mentioned, along with the pitch enlargement of unloading element, it is big that the overall diameter of annulus also becomes thereupon, formed thus and the opposite air movement of unloading component orientation.Revolution when also having caused the rotation of wire harness clamping device thus is lower than the rotation revolution of second clamping element at open position, air-flow in the wire harness clamping device to outer mobile.Although if adopted the structure that meets design concept of the present invention, but still there is contaminant infiltration to go into wire harness clamping device inside, then should it be removed from the wire harness clamping device.The wire harness clamping device that the present invention relates to this moment has the function of self-cleaning, and this function can be guaranteed the very high duration of runs.
When at least one section of stop surface matched with the truncated cone side, this design had advantage more.If the relative configurations place in the second clamping element associated outer surface can generate annulus above-mentioned, the advantage of so this structure is bigger.The retainer that has formed truncated cone like this in the position near second clamping element is centrally aligned with it, thereby has just begun concentric running at this stage second clamping element and retainer.
Equally advantageously, the stop surface of the outer surface of second clamping element and/or retainer is to be made up of the elastic sealing element form of sealing ring (for example with).This can strengthen the sealing effectiveness of retainer.Except the sealing ring that rubber or other elastomeric materials are processed, the associated outer surface of the retainer itself or second clamping element is also used the other materials manufacturing certainly, as long as this material can seal relevant slit very reliably.
First clamping element and retainer are fixed on above the rotary type top of spin spindle or twisting spindle independently of each other, also are a kind of favourable mentalities of designing.The retainer of this moment can become loop configuration and aforementioned stepped configuration once more again.First clamping element and retainer can press-fit or screw down and be fixed on the rotary type top.Perhaps also can direct as mentioned above retainer be fixed on first clamping element.The wire harness clamping device of an integral installation on the rotary type top of spin spindle or twisting spindle just appearred can be used as thus.
If the overall diameter of retainer is identical in the overall diameter size of retainer position with second clamping element, is favourable equally.So the outer surface of wire harness clamping device is level and smooth especially, and therefore in spinning or the winding process, the air drag that receives during the rotation of wire harness clamping device is very little, and is therefore lower in order to the energy demand that drives spin spindle or the twisting spindle that carry the wire harness clamping device.

The specific embodiment
Fig. 1 and Fig. 2 have showed the wire harness clamping device under the present prior art state.This wire harness clamping device mainly is installed on the spindle of spinning machine and wrapping machine (for example ring throstle or ring twisting machine etc.), is used for anchor yarns when changing bobbin.
Because it is known that the spindle of wire harness clamping device is configured in industry, so the single component of spindle is not intactly displayed on the accompanying drawing.A rotary type top 13 (together showing with the wire harness clamping device that meets design concept of the present invention among Fig. 8) and a non-rotatable bearing housing that is fixed on the spindle case are installed on the known spindle mostly.Rotary type top 13 also is wrapped in a together footstalk of rotation generally speaking in addition, and this footstalk is installed on the journal bearing and pin bearing (not showing among the figure) in the bearing housing.Rotary type top 13 also comprises an ingot pulley in addition, through it by a belt drives.The wire harness clamping device finally just is installed in the ingot pulley top.
The wire harness clamping device that meets design concept of the present invention of drawings show; Also be called the clamping drift; First clamping element 1 and centre bore 18 of being furnished with a sleeve-shaped; Through this hole, clamping element can join with Yarn-spinning spindle or the rotatable top 13 on the twisting spindle (referring to Fig. 7, Fig. 8) rotation of spinning machine or wrapping machine.For this reason can be in ring gear face 19 of the bottom of first clamping element 1 design (with Fig. 5 contrast); The engagement of the respective profile on the rotatable top 13 on it and Yarn-spinning spindle or the twisting spindle, thus guaranteed that the moment of torsion to necessity of wire harness clamping device transmits from rotatable top 13.
Here be stressed that first clamping element 1 and second clamping element 2 not necessarily leave no choice but be designed to a global facility.They can be made up of a plurality of interconnective discrete components as required on the contrary.
Next second clamping element 2 of a sleeve-shaped also has been installed on the wire harness clamping device, and it can move with respect to first clamping element 1, and outwards surrounds first clamping element 1 most.A load elements 4 that for example is made up of helical spring is installed between first clamping element 1 and second clamping element 2.The effect of load elements 4 is closed positions that second clamping element 2 is showed in moving to like Fig. 1, and the corresponding anchor clamps jaw 14,20 of first clamping element 1 and second clamping element 2 was in contact with one another in the position of last clamp segment 3 and was meshing with each other this moment.
In addition; For second clamping element 2 is moved to the open position of showing among Fig. 2; Need on the wire harness clamping device, to install a plurality of unloading elements 5, for example with the form of spheroid, this element receives the guiding that a rotating shaft with the wire harness clamping device is the conduit that radially extends.If this moment, rotary type top 13 rotated together with the wire harness clamping device, will apply one with its centrifugal force that outwards pushes to unloading element 5 so.They contact with the interactive truncated cone shape ring surface 15 of second clamping element 2 here.By the time wire harness clamping device rotation reaches certain revolution, and centrifugal force becomes greatly thereupon, and the load elements 4 that receives during in the closed position greater than second clamping element 2 until the active force that unloads 5 pairs second clamping elements 2 of element is to its power that applies.Finally cause second clamping element 2 to move to the open position of showing among Fig. 2 thus, the anchor clamps jaw 20 of second clamping element 2 is away from the anchor clamps jaw 14 of first clamping element 1 herein, thereby makes the position of clamp segment 13 annulus occur.Article one, line tail complete, that be installed in the bobbin on the wire harness clamping device finally just inserts in this slit.
After inserting so-called underwinding line, the revolution of spindle will reduce, and the centrifugal force that acts on unloading element 5 diminishes thereupon, is not enough to second clamping element 2 is maintained its open position.Cause second clamping element 2 to move axially thus, finally clamping lines tail as expection.And then the line that twines from the bobbin residue breaks off, so that complete bobbin is taken off from spindle.
Put a new ceases to be busy axle, continue then to spin and twist thread.Yarn this moment (its terminal line tail has been used a wire harness clamping device clamps) beginning is twined on bobbin, need not fix need not also to worry that yarn comes off within a certain period of time again with the wire harness clamping device.Increase once more from the revolution of spindle at the moment, and move to its open position under the action of centrifugal force that second clamping element 2 occurs herein again, reserved necessary clamping slit in clamp segment 3 positions for change bobbin next time thus.
Show as Fig. 1 and Fig. 2, have an annulus 17 between first clamping element 1 and second clamping element 2, can realize friction free relative motion as far as possible between first clamping element 1 and second clamping element 2 by this slit.But pollutant (for example dust) also might be penetrated in the device inner chamber 9 of placing unloading element 5 through slit 17.If pollutant is piled up there, so just might hinder the mobile of unloading element 5 or it is blocked.The accessible running of wire harness clamping device can't be guaranteed in this case, and processing must be cleaned and change accordingly.
In order to solve this defective, according to design concept of the present invention, at least one retainer 6 is installed in suggestion on the wire harness clamping device, and just first topology example as the wire harness clamping device of showing among Fig. 3 and Fig. 4 that the present invention relates to is the same.Retainer 6 comprises a stop surface 7, and this stop surface 7 at least one outer surface 8 through it when second clamping element 2 is shown in an open position closely pastes with stop surface 7 mutually.
As shown in Figure 4, so can effectively avoid pollutant to be penetrated into the inner chamber 9 that surrounds unloading element 5 from the position of retainer 6.In example, stop surface 7 ringwise, retainer 6 itself is the part of first clamping element 1, and is unified whole with one of its formation.Certainly the retainer 6 and first clamping element 1 also can be made up of a plurality of parts, but must interconnect with appropriate mode.
The stop surface 7 of an annular is housed, as axial retainer 6 uses of second clamping element 2 on this wire harness clamping device.For this reason, be equipped with the outer surface 8 of an annular on this clamping element equally, when second clamping element was shown in an open position, this outer surface closely pasted with stop surface 7 mutually.First clamping element 1 closely has been connected with slit 17 between second clamping element 2, thereby dust no longer maybe be from be penetrated into inner chamber 9 here.In order to prevent that the most tiny particulate is penetrated in the interior wall, in addition can also image pattern 3 with Fig. 4 in that kind of showing, a seal 12 is installed, such as a sealing ring is installed on the retainer 6 and/or second clamping element 2.
Above-mentioned diagram shows further that also one section interior diameter that inner chamber 9 extends out is more preferably greater than that section interior diameter at unloading element 5 places on unloading element 5.A benefit is arranged like this, the pollutant that promptly gets into inner chamber 9 from the relevant slits in clamp segment 3 zone be deposited under the action of centrifugal force unloading element 5 above.So under any circumstance can both avoid pollution unloading element 5, thereby guarantee that the wire harness clamping device can keep the long duration of runs from the top.
Other a kind of structure that Fig. 5 (open position) and Fig. 6 (closed position) have showed the wire harness clamping device that this invention relates to.Different with the structure of top introduction, the stop surface 7 of second clamping element here and the outer surface 8 of staggered form all have one section lateral side regions 11 with truncated cone to match.As showing among the figure, be in addition outer surface 8 or stop surface 7 all to show a cross section be stair-stepping profile, profile comprises two adjacent with lateral side regions, best ring surfaces of extension radially.
This structure of mentioning above sees all have advantage from many aspects.Because the stepped configuration of outer surface 8 and stop surface 7, consequent annular contact surface (referring to Fig. 6) is compared with non-stepped configuration, and its upper surface is big especially.Therefore pollutant must pass also so that big contact-making surface could get in the inner chamber 9 of wire harness clamping device, just can pollute the part that unloads element 5 sensitive for damages.
Also showed another one innovation part among Fig. 5 and Fig. 6, i.e. the truncated cone of downward outer surface 8 interludes of the stop surface 7 and second clamping element 2.In Fig. 5, can see especially; When it is in the closed position; Formed an annulus 16 between second clamping element 2 and the retainer 6, the interior diameter of the outer surface 8 of the overall diameter of stop surface 7 and second clamping element 2 reduces along the direction of unloading element 5 gradually.If let the rotation of wire harness clamping device this moment, then the air at 16 places, annulus forms centrifugal force.The centrifugal force of 16 perimeters, annulus is higher than interior zone.Therefore the radial direction at wire harness clamping device rotating shaft generates one air-flow.When second clamping element 2 was in the closed position, this strand air-flow acted on contaminant infiltration in retainer 6 positions conversely, so that whenever protection unloading element 5 can not polluted.
Fig. 7 and Fig. 8 have showed last topology example.Retainer 6 is independent parts in this example, perhaps links to each other with first clamping element 1, perhaps links to each other with rotary type top 13 independently.Can imagine and corresponding pressing or other forms of mechanical connection in this combination, must occur.Be furnished with an annular shoulder spare 10 on the retainer 6 this moment, and it can provide the stop surface 7 an of necessity, so that to the moving axially of limit second clamping element 2, and guarantees inner chamber 9 is carried out necessary sealing.
Final purpose of the present invention is that a kind of pollutant of can avoiding of design is penetrated into around the wire harness clamping device the inner chamber 9 of unloading element 5 from the position of retainer 6.In addition can be according to the relevant explanation of above-mentioned and inner chamber 9 structures, the pollutant of guaranteeing to get into inner chambers 9 from clamp segment 3 arrive unload element 5 before, just be deposited on second clamping element and be positioned at the respective inner walls position that unloads element 5 fronts.
In addition, this invention is not limited to the above topology example of showing.On the contrary, as showing in claim introduction and the diagram and explaining, the various combinations of above-mentioned single characteristic all belong to category of the present invention, as long as possess realizability on this combination technique, and are significant.
